Abstract
In Tasmanian waters Australian fur seals, Arctocephalus pusillus doriferus, breed on five islands in Bass Strait with non-breeding haul-out sites situated in Bass Strait and along the south-eastern and southern Tasmanian coastline. Estimates of pup production were obtained over four breeding seasons between 1989 and 1993 by aerial photography, ground counts and mark-recapture censuses. Pupping commences in late October, with 90% of pups born between 2 and 20 December. Pup mortality is estimated at 15% by early January, when ground censusing was conducted. Pup production of breeding colonies in Tasmanian waters was highest in 1991, with 5130 pups estimated to have been born.
